Abstract
Background Hypertension is the most important modifiable cardiovascular risk factor among women. Chronic kidney disease (CKD), which affects 1 in 10 reproductive-aged women, increases the risk of hypertension; however, awareness of hypertension in this population is unknown. This study aimed to determine hypertension awareness among reproductive-aged women living with chronic kidney disease. Methods Women aged 18 to 50 years with CKD were recruited from nephrology clinics in Calgary, Alberta, Canada. Participants completed a semistructured interview and focused chart review, serum and urine laboratory assessment, and a physical examination that included anthropomorphic measurements and 2 automated office blood pressure readings. Hypertension was defined according to the use of ≥ 1 antihypertensive medications and/or an automated office blood pressure reading of ≥ 135/85 mm Hg. Data were stratified by hypertension status, as well as by awareness, and descriptively presented as mean ± standard deviation, numerical values, and percentages. Results Sixty-three participants with CKD were included. Thirty-eight (60%) participants had hypertension according to study definitions. Of those with hypertension, 30 participants (79%) were aware of their hypertension status. Conclusions Hypertension awareness is relatively high in reproductive-aged women living with CKD. However, hypertension awareness is the critical component for hypertension management, and further work is necessary to optimize reduction of cardiovascular risk in this important population.

The Association Between Testosterone and Vascular Function in Reproductive-Aged Females With Chronic Kidney Disease. CJC Open 2024; 6:530-538. [PMID: 38487057 PMCID: PMC10935681 DOI: 10.1016/j.cjco.2023.11.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 11/07/2023] [Indexed: 03/17/2024] Open
Abstract
Cardiovascular disease is the leading cause of death in women, and women with chronic kidney disease (CKD) experience especially elevated risk. This study examined the association between testosterone and vascular function in 61 reproductive-aged females with CKD. Testosterone levels and measures of vascular function were assessed, including pulse wave velocity, aortic augmentation, flow-mediated dilation (FMD), and velocity time integral. Multivariable linear regression analyses assessed the relationship between testosterone and each measure of vascular function. No associations were observed between testosterone and vascular function outcomes, although a significant positive association between testosterone-to-estradiol ratio and FMD was demonstrated. Although testosterone levels were not independently predictive of vascular function, the level of testosterone relative to estradiol was associated with FMD and may therefore influence endothelial function in the high-risk population of reproductive-aged female patients with CKD.

Association of insomnia and short sleep duration, alone or with comorbid obstructive sleep apnea, and the risk of chronic kidney disease. Sleep 2022; 45:6571834. [PMID: 35445715 PMCID: PMC9272259 DOI: 10.1093/sleep/zsac088] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 04/07/2022] [Indexed: 11/14/2022] Open
Abstract
STUDY OBJECTIVES Obstructive sleep apnea (OSA), sleep fragmentation, and short sleep duration (SD) have been associated with chronic kidney disease (CKD). However, these potential mechanisms for CKD have not been compared in the same cohort. This study investigated the independent and combined impact of OSA and insomnia with short sleep duration on the risk of CKD progression in a sleep clinic population. METHODS In a cross-sectional study design, adults with suspected OSA completed an overnight sleep study and a questionnaire that included the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI). They also provided blood and urine samples for measurement of the glomerular filtration rate and urine albumin:creatinine ratio, from which the risk of CKD progression was determined. RESULTS Participants (n = 732, 41% female, 55 ± 13 years) were categorized into four groups: no/mild OSA without insomnia (NM-OSA, n = 203), insomnia with SD without OSA (Insomnia-SD, n = 104), moderate-to-severe OSA without insomnia (MS-OSA, n = 242), and comorbid insomnia and OSA with SD (COMISA-SD, n = 183). After stratification, 12.8% of NM-OSA, 15.4% of Insomnia-SD, 28.9% of MS-OSA, and 31.7% of the COMISA-SD participants had an increased risk of CKD progression. Compared to NM-OSA, the odds ratio (OR) for an increased risk of CKD progression was not increased in Insomnia-SD (OR 0.95, confidence interval [CI]: 0.45-1.99) and was increased to the same degree in MS-OSA (OR 2.79, CI: 1.60-4.85) and COMISA-SD (OR 3.04, CI: 1.69-5.47). However, the ORs were similar between the MS-OSA and COMISA-SD groups across all statistical models (p ≥ .883). CONCLUSIONS In a sleep clinic population, insomnia with short sleep duration does not increase the risk of CKD progression; nor does it further increase the risk of CKD progression associated with moderate-to-severe OSA.

Abstract
OBJECTIVE To estimate the prevalence of chronic kidney disease (CKD) in the adult Brazilian population and to describe its characteristics, according to the National Health Survey (PNS) 2013-2019. METHODS Descriptive cross-sectional study, with adults participating in the PNS, based on self-reported medical diagnosis of CKD. Prevalence of CKD and their respective 95% confidence intervals (95%CI) were estimated for Brazil. RESULTS In 2013, 60,202 individuals were analyzed, and in 2019, 85,854. The prevalence of self-reported diagnosis of CKD in both editions was 1.4% and increased with increasing age. In 2019, the prevalence of self-reported CKD was 3.3% (95%CI 2.9;3.7) in hypertensive individuals, 4.1% (95%CI 3.4;5.0) among diabetics, and 3.3% (95%CI 2.8;3.9) in those reporting hypercholesterolemia. CONCLUSION The prevalence of CKD in Brazil remained stable in the period but reinforces the need for expansion of diagnosis and strengthening of primary care in the Brazilian National Health System (SUS).

Abstract
BACKGROUND OSA is common in chronic kidney disease (CKD) and may accelerate a decline in kidney function. It is not clear whether treatment of OSA with CPAP improves kidney function. RESEARCH QUESTION Does treatment with CPAP improve kidney function in patients with CKD and coexisting OSA? STUDY DESIGN AND METHODS A randomized, controlled, nonblinded, parallel clinical trial was performed of patients with stages 3 and 4 CKD and coexisting OSA comparing the effect of CPAP vs usual care on the estimated glomerular filtration rate (eGFR) and the urine albumin to creatinine ratio (ACR) over 12 months. RESULTS Fifty-seven patients were enrolled and 30 were randomized to CPAP. They had moderately severe CKD (eGFR, 38.4 ± 1.5 mL/min/1.73 m2) and significant OSA and nocturnal hypoxemia (oxygen desaturation index: 23.9 events/h; interquartile range [IQR], 20.3 events/h; mean peripheral capillary oxygen saturation: 89.5%; IQR, 1.7%); 60% had baseline albuminuria (ACR, > 3 mg/mmol). No significant difference was found between CPAP and usual care in the change in eGFR and ACR over 12 months. Although some improvement in eGFR occurred with CPAP therapy in patients with a lower risk of CKD progression, this did not reach statistical significance. INTERPRETATION Although CPAP did not provide additional renal benefits over usual care in all CKD patients, some evidence suggested that CPAP slowed the decline in eGFR in CKD patients with a lower risk of CKD progression. These preliminary data support the need for larger clinical trials exploring the effects of CPAP on kidney function. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT02420184; URL: www.clinicaltrials.gov.
